i can get data with itextsharp just and empty grid.
ineed that if shows in the pdf the associated image as i do in gridview see my code:
bool gerarpdf;
protected void btn_pdf_Click(object sender, ImageClickEventArgs e)
{
gerarpdf = true;
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
/* Necessario para gerar pdf com gridview */
}
protected override void Render(HtmlTextWriter writer)
{
if (gerarpdf == true)
{
//pdf generation code called here
int columns = GridView2.Columns.Count;
// Table and PdfTable classes removed in version 5.XXX
iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(columns);
// padding can only be set for cells, __NOT__ PdfPTable object
int padding = 5;
float[] widths = new float[columns];
for (int x = 0; x < columns; x++)
{
widths[x] = (float)GridView2.Columns[x].ItemStyle.Width.Value;
string cellText = Server.HtmlDecode(GridView2.HeaderRow.Cells[x].Text);
// Cell and Color classes are gone too
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new iTextSharp.text.Phrase(cellText))
{
BackgroundColor = new iTextSharp.text.BaseColor(
System.Drawing.ColorTranslator.FromHtml("#008000")
),
Padding = padding
};
table.AddCell(cell);
}
// next two lines set the table's __ABSOLUTE__ width
table.SetTotalWidth(widths);
table.LockedWidth = true;
for (int i = 0; i < columns; i++)
{
if (GridView2.Rows[i].RowType == DataControlRowType.DataRow)
{
for (int j = 0; j < columns; j++)
{
string cellText = Server.HtmlDecode(GridView2.Rows[i].Cells[j].Text);
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new iTextSharp.text.Phrase(cellText))
{
Padding = padding
};
if (i % 2 != 0)
{
cell.BackgroundColor = new iTextSharp.text.BaseColor(
System.Drawing.ColorTranslator.FromHtml("#C2D69B")
);
}
table.AddCell(cell);
}
}
}
Response.ContentType = "application/pdf";
iTextSharp.text.Document pdfDoc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10f, 10f, 10f, 0f);
iTextSharp.text.pdf.PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
pdfDoc.Add(table);
pdfDoc.Close();
Response.End();
}
else
{
//let page render normally
base.Render(writer);
}
}
}
need with paggin option i found a demoe here but i dont know here to put it into my code http://archive.aspsnippets.com/demos/GridView2PDF.aspx
what i need is sothinng similar to this but also with pagging
http://www.aspsnippets.com/Articles/Export-GridView-with-Images-to-Word-Excel-and-PDF-Formats-in-ASP.Net.aspx
i have an error that is easy fixed by setting the width because the error says table width must be grater than zero so i think this is not caculating the width so how could i set it to calculate it self than i fix manually
but its strange why do not have width i just see this line in code:
edit: with autosize in column width it gets 0.0 of width so its why i get the error but how to fix it without putting the values?
should i create a function to do he job and pass it to the avriable but how?
also have found on another site how to set a column width n percentage but i dont know where to add it on my code.
the code i found was
/*
* default table width => 80%
*/
table.WidthPercentage = 100;
// then set the column's __relative__ widths
table.SetWidths(new Single[] {1, 5, 4});
/*
* by default tables 'collapse' on surrounding elements,
* so you need to explicitly add spacing
*/
table.SpacingBefore = 10;
for (int i = 0; i < col.Length; ++i) {
PdfPCell cell = new PdfPCell(new Phrase(col[i]));
cell.BackgroundColor = new BaseColor(204, 204, 204);
table.AddCell(cell);
}
for now i have set the width on itemstyle manually to 20% for each collumn (20%*5 collumns=100%)
I would suggest to start from a simple code. Get rid of colors, width, paddings and other formatting. Be sure that the text goes to right cells and after that try to format the table.

I tested your code and it looks like it is due to
int padding = 5;
If I change it to 1..4 I see the text. With 5 it disappears.

1..4 meaning 1 to 4, not 1.4

It's up to you. I tested your code and found that if I use 5 as per your example, the text goes away. If I change to 1 or to 4 - it is visible.
Simply change it and see if it looks properly for you.

but i cant see nothing no data into it
